The A354 is a primary route in England which runs from Salisbury in Wiltshire to Easton on the Isle of Portland in Dorset, a total distance of 51 miles (82 km).

After the old and new sections meet at Manor Roundabout the road follows down Weymouth Way alongside Radipole Lake.

The project was to build a 3.75-mile (6.04 km) single carriageway road, with crawler lane along part, linking the A354 Manor Roundabout near Radipole to the A354 at the top of the Ridgeway Hill.

Following the lapse of permission Dorset County Council undertook a review of the previously consented scheme.

As a result of the council's re-assessment, changes were made to the September 2005 proposals, primarily to the stretch of road through the Area of Outstanding Natural Beauty.
